What are the challenges that SRM tools face? Is the problem one of scale and complexity? If you look at what we expect the SRM tool to do, we expect currently expect it to understand our storage environment end-to-end. So look at what an SRM tool needs to do.
Understanding the reasons for migration is a great place to start in developing a strategy. Seasoned IT professionals will know that change for changeâ€™s sake is not a good thing; â€œif it ainâ€™t broke, donâ€™t fix itâ€ â€“ the old adage says, for good reason. Data migrations will introduce change into an environment and with change comes risk. However there are practical reasons to perform migrations.
Stephen has a post here about pricing, about getting close to your vendor and developing a relationship with just a few trusted partners. Nice idea but in any relationship there needs to be some tension to keep it fresh and alive; otherwise you find yourselves doing something because you have always done so, it becomes comfortable.
HP Storage Products traditionally have support for RAID 0, RAID 1, RAID 1+0, RAID 5 and now RAID-6 ADG.
Continuing the quest on RAID 6, with my previous post related to HDSâ€™s RAID 6, here is a post about NetAppâ€™s RAID-DP (Double Parity – Enhanced RAID 6).
Hitachi (HDS) has been one of the pioneers in implementing RAID 6 in their storage products. This technology briefing covers HDS’ implementation of RAID 6 and compares it to their RAID 5 implementation.
We think of web apps as what belongs in the â€œcloudâ€. Virtualization is changing this so that both small and enterprise apps are a fit. To me there can be an internal cloud and an external cloud. As virtualization continues to evolve, we will see the lines blur between both.
At the moment, Enterprise Flash disks are all being used as faster spindles; as faster replacements to spinning rust. In the same way that I could remove my laptop/pc drive and replace it with a SSD; I can do it in an array at some extortionate price.I know thereâ€™s been a fair amount of tweaking to get them into the various arrays but it doesnâ€™t appear to be the proverbial rocket science! So can we have some rocket science now?
Mike DiPetrillo from VMware just blogged about a new VMware knowledge base article fosuced on how VMware writes I/O to disk. This is essential reading for any VMware admin, as it deals with each OS’s I/O idiosyncracies.
Capital budgets are pretty tight this year and IT teams all over the globe are being to do more with the same or less. This is good in many ways and hopefully we will overcome some of the profligacy of the past but the responsibility is in our (the end-users) hands, we canâ€™t simply expect the vendors who have encouraged of profligacy in the past to come riding to our rescue.
